galran Repair containing vitamins (galanthamine) and ( Amaryllidaceae ) of the plant precipitate the galantamine hydrobromide (galanthamine hydrobromide) in a mixture of alkaloids (alkaloids) was obtained in the alkali (alkali) treatment the hydrobromide (hydrobromide) salt, and then extracted, galanthamine with a solvent of the general formula ( ) (galanthamine) with galantamine (galanthamine) ( ) purification method consists in crystallizing the,Here, R 1 is hydrogen (hydrogen) or methyl (methyl), R 2 is n - butyl ( n -butyl, isobutyl (isobutyl), 2-tert-butyl ( sec -butyl) and t - butyl ( t is selected from the -butyl),The obtained pure galantamine (galanthamine) can be conveniently used in the manufacture of galantamine hydrobromide (galanthamine hydrobromide).갈란타민(galanthamine)을 함유하는 수선과(Amaryllidaceae)의 식물에서 획득된 알칼로이드(alkaloids)의 혼합물에서 갈란타민 하이드로브로마이드(galanthamine hydrobromide)를 침전시키고, 알칼리(alkali)로 하이드로브로마이드(hydrobromide) 염을 처리하고, 추출한 다음, 일반적인 구조식(Ⅱ)의 용매로 갈란타민(galanthamine)을 결정화시키는 것으로 구성된 갈란타민(galanthamine)(Ⅰ) 정제 방법으로,여기서, R1은 수소(hydrogen) 또는 메틸(methyl)이고, R2는 n-부틸(n-butyl, 이소부틸(isobutyl), 2급-부틸(sec-butyl)과 t-부틸(t-butyl)에서 선택되며,얻어진 순수한 갈란타민(galanthamine)은 갈란타민 하이드로브로마이드(galanthamine hydrobromide)의 제조에 편리하게 사용될 수 있다.
